Abstract excerpt
Seeds of the lethal embryo 1 (lem1) mutant in maize (Zea mays) display a non-concordant lethal phenotype: whereas the embryo aborts very early, before the transition stage, the endosperm develops almost normally. The mutant was identified in a collection of maize lines that carried the transposon Activation (Ac) at different locations in the genome. Co-segregation and reversion analysis showed that lem1 was...
